Bug #: 32989 Summary: Orcs Must Die! 2 sometimes crashes when level completed Product: Wine Version: 1.5.24 Platform: x86 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown AssignedTo: wine-bugs@winehq.org ReportedBy: jeff@deseret-tech.com Classification: Unclassified
Orcs Must Die! 2 will sometimes (probably about 50% of the time) crash when the last wave of enemies is completed instead of displaying the level completion screen. Since each level can take 20 minutes or more to complete this is rather frustrating.
There is no output to the console (without debug options) when the crash occurs. There is no illegal operation notice, the game just disappears.
This has also been reported in the comments on the game's AppDB entry, back in August 2012. I played often in October 2012 without encountering the issue, however.
